Description
Restore hydration, strength and shine with this two-step OLAPLEX hair care duo, designed for dry, dull, damaged and chemically treated hair. Combining gentle cleansing with intensive conditioning, it helps improve softness, manageability, smoothness and the appearance of damaged strands.
Nº.4 Bond Maintenance Shampoo gently cleanses using coconut-derived surfactants that create a rich lather without stripping essential moisture. Its patented bond-building technology, powered by Bis-Aminopropyl Diglycol Dimaleate, helps strengthen compromised hair bonds and improve hair resilience. Glycerin, panthenol, sodium hyaluronate and botanical extracts support hydration and conditioning, while sunflower, apricot and argan-derived oils help maintain softness.
Rich Hydration Mask provides intensive conditioning through Biomimetic Cuticle Technology, designed to seal the hair cuticle and retain moisture for up to five washes. Its Avocado and Shea Conditioning Complex combines avocado oil, shea butter, sunflower, coconut, safflower and other nourishing oils to soften dry hair, improve flexibility and enhance shine. Glycerin and propanediol support hydration, while Behentrimonium Methosulfate and Behentrimonium Chloride improve detangling and smoothness.
Both formulas contain Bis-Aminopropyl Diglycol Dimaleate, complementing the duo’s bond-focused approach. Together, their bond-building, moisture-binding and cuticle-conditioning technologies help reduce the appearance of breakage, dryness and frizz while improving hair manageability and shine.
The experience is complemented by OLAPLEX’s signature light, clean and subtly sweet fragrance, featuring refreshing grapefruit and mint notes. Suitable for colour-treated and chemically treated hair, this duo leaves strands softer, smoother, hydrated and healthier-looking.
The combination helps repair everyday hair damage in just one wash, while delivering up to 16x more hydration instantly and maintaining 6x more hydration after five washes. It also provides 119% more shine, leaving hair visibly smoother, softer, more hydrated and healthier-looking.
